Solved Show that sigma^n_k = 1 k = 1 n(n + 1)/2 for all n
The exponent says how many times to use the number in a multiplication. A negative exponent means divide, because the opposite of multiplying is dividing. A fractional exponent like 1/n means to take the nth root: x (1 n) = n√x. If you understand those, then you understand exponents!

n! = n × (n−1)! Which says "the factorial of any number is that number times the factorial of (that number minus 1) " So 10! = 10 × 9!,. and 125! = 125 × 124!, etc. What About "0!" Zero Factorial is interesting. it is generally agreed that 0! = 1.

The Triangular Number Sequence is generated from a pattern of dots which form a triangle: By adding another row of dots and counting all the dots we can find the next number of the sequence. But it is easier to use this Rule: x n = n (n+1)/2. Example: the 5th Triangular Number is x 5 = 5 (5+1)/2 = 15,

28 Find limn→∞((n!)1/n) lim n → ∞ ( ( n!) 1 / n). The question seemed rather simple at first, and then I realized I was not sure how to properly deal with this at all. My attempt: take the logarithm, limn→∞ ln((n!)1/n) = limn→∞(1/n) ln(n!) = limn→∞(ln(n!)/n) lim n → ∞ ln ( ( n!) 1 / n) = lim n → ∞ ( 1 / n) ln ( n!) = lim n → ∞ ( ln ( n!) / n)

Home GCSE MATHS Number Number Sequences In the sequence 2, 4, 6, 8, 10. there is an obvious pattern. Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8. Number Sequences

Rather (n+1)!= (n+1)(n)(n−1)! now just cancel it with (n−1)! thats all. Solve for k ∈ Z such that f (19992π) = 2k1 where f (x) = ∏n=1999 cos(nx). You are on the right track. But you need to do this not mod p but modulo pα, where α is the largest power of p dividing n.
